Sebagai contoh, penelitian sebelumnya menyebutkan bahwa hiu mempunyai rambut halus atau cara memanipulasi skala perubahan arah saat melakukan gerakan cepat. Kelincahan ini sangat penting bagi hiu untuk menangkap mangsa yang juga bergerak cepat, misalnya tuna.

Environmental advocates in Hong Kong say that opposition gathered steam this year amid rising awareness of how many sharks are being killed — 100 million a year — and of how their prized fins are harvested. Usually the fins are cut off a living fish that is then thrown back into the water to die.

The Great White Shark is a macropredator found mainly in temperate seas and oceans, but the Great White Shark can also occasionally enter tropical waters. It is principally an epipelagic dweller, which means that it can typically be found in the uppermost layers of the ocean; normally between the ocean surface and the thermocline at a depth of roughly 200 meters. 

(From The Washington Post  / by Juliet Eilperin) - For years, humans have thought of great white sharks wandering the sea at random, only occasionally venturing close to shore. We were wrong.

Tahukan Anda, Indonesia memiliki spesies ikan hiu yang biasa berjalan di dasar lautan? Hiu yang bernama latin Hemiscyllium galei dan Hemiscyllium henryi tersebut dijuluki walking shark (hiu berjalan) yang ditemukan di perairan Raja Ampat, Kawasan Kepala Burung Papua Barat. Hiu berjalan ini adalah satu dari 11 species biota laut baru yang ditemukan Lembaga Ilmu Pengetahuan Indonesia (LIPI).

Popularitas sup mahal ini juga menyebar di seluruh dunia. Akibatnya banyak spesies ikan hiu sekarang menghadapi risiko kepunahan.

Endangered orangutans live on two islands, Sumatra and Borneo, in Asia. Some estimates suggest that orangutans could become extinct within the next decade or two. Threats to their survival include habitat loss and illegal pet trade. Their slow reproduction rates also contribute to the problem.

If current logging trends continue, most of Indonesia's National Parks are likely to be severely damaged within the next decade. They are amongst the last areas to hold valuable timber in commercially viable amounts.

White sharks are predatory animals that begin life by feeding on fish, rays, and other sharks, and as they grow, switch to feeding on marine mammals and scavenging on large animal carcasses. Their first mammalian prey are usually the small harbor seal, but as the sharks increase in size, they become large enough to eat sea lions, elephant seals, and small toothed whales. Attack strategy consists of a swift, surprise attack from below, inflicting a large, potentially fatal bite. The pinniped often dies from massive trauma or blood loss, but the bites may be superficial or misplaced on the body, allowing the seal to escape and survive the attacks with their scars as witness. Large white sharks will also scavenge on the carcasses of whale sharks, and on the fat-rich blubber layer of dead whales. They will occasionally feed on sea turtles and sea otters, and are known to attack, but not eat, humans.

Of the 100-plus annual shark attacks worldwide, fully one-third to one-half are attributable to great whites. However, most of these are not fatal, and new research finds that great whites, who are naturally curious, are "sample biting" then releasing their victims rather than preying on humans. It's not a terribly comforting distinction, but it does indicate that humans are not actually on the great white's menu.

All we are know that this animal is so dangerous. They are The TOP PREDATOR inside our ecosystem. But now they sow a legendary new enemy and the enemy is us. We can't eat tigers steak, but why we hunt them?.

Most cats do not like getting wet - as anyone who has tried to bathe a moggie will know. But as these pictures show, there's always the exception to the rule. For the cat in question is a large male white Bengal tiger called Odin.

Six years old, and at the prime of his life, Odin lives at the Six Flags Discovery Kingdom Zoo in Vallejo, near San Francisco. He is about 10ft long from nose to tail, and is an excellent swimmer.

Odin was hand-raised at the zoo. And after he was weaned, his British trainer Lee Munro discovered his remarkable skill: when a lump of meat was thrown into a pool of water, Odin would happily dive in after it.

Harimau Sumatra atau dalam bahasa latin disebut Panthera tigris sumatrae merupakan satu dari lima subspisies harimau (Panthera tigris) di dunia yang masih bertahan hidup. Harimau Sumatera termasuk satwa langka yang juga merupakan satu-satunya sub-spisies harimau yang masih dipunyai Indonesia setelah dua saudaranya Harimau Bali (Panthera tigris balica) dan Harimau Jawa (Panthera tigris sondaica) dinyatakan punah.

Hewan dari filum Chordata ini hanya dapat diketemukan di Pulau Sumatera, Indonesia. Populasinya di alam liar diperkirakan tinggal 400–500 ekor. Harimau Sumatera (Panthera tigris sumatrae) semakin langka dan dikategorikan sebagai satwa yang terancam punah.

The Sumatran tiger occurs in about 58,321 km² of forested habitat in 12 potentially isolated Tiger. Conservation Landscapes totalling 88,351 km² (Sanderson et al. 2006), with about 37,000 km² protected in ten national parks (Govt of Indonesia 2007). The tiger population was estimated at 400-500 in the first and second national tiger action plans (Govt of Indonesia 1994, 2007a), and at 342-509 in six major protected areas (estimates from Shepherd and Magnus 2004). However, incorporating more recent research, covering most of tiger estimated habitat (Sanderson et al. 2006) suggests the population could be higher (see Table 1 in attached PDF).

There is no recent information from Berbak or Gunung Leuser, and both of these estimates are considered speculative. Completion of a research in the three Tiger Conservation Landscapes in Riau province by Sunarto et al. (2007) will improve efforts to assess the Sumatran tiger population.

KOMPAS.com - Perburuan harimau Sumatera (Phantera tigris sumatrae) terus berjalan. Dari 20 kota di delapan provinsi di Sumatera yang dipantau oleh TRAFFIC (sebuah organisasi non pemerintah yang aktif memantau perdagangan satwa liar), 13 di antaranya menjadi tempat lalu lintas perdagangan organ tubuh harimau. Satu-satunya tempat yang menjadi populasi terbesar harimau endemis di Sumatera itu hanya ada di Taman Nasional Gunung Leuser di Sumatera Utara dan Nanggore Aceh Darussalam (NAD).

There's generally a lack of communication between professionals and amateur collectors/dealers, and new ideas are published and "made into scientific law" by a select few. Although well-intentioned and done by well-respected individuals, the professionals generally don't have access to the bulk material from all areas needed to make completely informed decisions. Amateur collectors/dealers (99.9% of the fossil community) will often have better "common knowledge" and will have seen a wider variety of fossil material. This is the untapped mine of information from which I draw my conclusions in the following article.
